To a, wlwm/ it may concern:

Be it known that l, .lumus SCIIIRRA, a citizen of the United States, residing at Pittsburg, in the county ol Allegheny and State of lriuisylvania, have invented certain. new and uscl'ul lmprovenumts in Anchoria; Devici-s for Concrete Construction, of which the following is a spm ilication, reference being had therein to the accompanying drawings, forming part of the specification, in which Figure 1 is vertical cross-sectional view of a portion of floor construction embodying my improved anchoring devices. Fig. 2 is a partial cross-section thereof on the line I I I I of Fig. 1. Fig. 3 is a plan view of one complete bar provided with assembled anchors. Fig. 4 is a partial side elevation thereof. Fig. 5' is an end view. Fig. 6 is a similar View showing a supplemental securing-clip. Fig. 7 is a detail perspective view of one of the Fig. 8 is a similar view of one of the clips. Fig. 9 is a detail view illustrating a corrugated extremity.

My invention refers to improvements in means for'binding or anchoring cement or concrete, and is particularly adapted for incorporation therewith in buildings, bridges, or other similar structurrs and it consists of a supporting-bar or similar element provided with one or more attached anchoring devices having extremities arranged in such a manner as to extend in various directions, so that when embedded in the concrete they will engage and maintain therewith a firm binding hold. The bars are designed to be incorpo rated with the structural elements of the building and to form a partial support for the concrete, being arranged sufficiently near together so that when the concrete is hardr-nrd they will become permanent portions of the concrete structure.

Referring to the drawings, 2 rep resents the I-bcams or other structural elements forming the framework of the building with which the floor is incorporated and between which the cement or concrete filling 3 is placed in the usual manner.

4 represents a bar of light structural shape, as a T, angle, Lbeam, channel, 630., adapted to be arranged between and supported upon the flanges of any two ad jaccnt beams, as shown in Fig. I, the bar 4 being provided with one or more, preferably several, anchors 5. As shown in the drawings, these anchors are formed of strips of short metal split at the ends and separated so as to provide divergent extremities 6 at each side of the bar 4, around which the strip is-bent and to which it conforms, as clearly shown, As thus constructed, sovrral of these anchors are assenibled along the bar and adjusted to proper location, and when the flooring material 3 is filled in they will become embedded and operate to firmly bind together and support the floor in the manner referred to.

In Fig. 6 I have shown clip 7 bent around in U form adapted to cmorace the web portion of the beam 4 and provided with outward ly-extending extremitirs 8, having slots or openings 9, through which the extremities 6 are passed and then bent over and separated outwardly, as shown. struction they are more securely connected with the bar, and the clip also provides additional holding elements for the cement.

It will be understood that the anchors may be made in different designs or forms and that the number of extrrmilir s may be varied, but such constructions are considered to be within thg scope of the invention and claims. The extremities 6 and 8 may. if drsirrd. he corrugated or bent in any manner so as to provide roughened l'iolding-farws, thus increasing the efiicir-ncy and binding hold, as in Fig. 9. As will be readily seen, the anchors may be adjusted lo1'igitudim1lly of the bar, and, if drsired, may be secured in position in any suitable manner, as by riveting or otherwise.

A special advantage of the invention is that the parts may be shipped separatrly in very compact packagi s or in bulk and readily and easily assembled at the point of use, while the number of anchors to be used on a single bar may be varied within the jiidgmr-nt oi the user.

The device-is very simple in ronstrin-lion, economical in cost, b1 ing made out of sheet metal without waste, and prrl'orms its functions in a satisfactory and (illUltllb inaninr.

Having described my invention, what I claim is l. The combination with a siipporting-bar, of a sheet-metal anchoring device brnt to rmbrace the supporting-lmr and provided with oppositely disposed diverging holding ex- By this contr mities and ai holding-olip arranged to emwith terminals engaging said anchoring device, substantially as set forth 2. An anchoring device consisting of a sheet-Inetalolip bent to conform to asupporting-bar and having oppositely-disposed diverging holding extremities, with a holdingolip adapted to surroundthe other side of the bar and provided with portions arranged to enga e said extremities and to bind them to -said or, substantially as set forth.

3. The combination with a supporting-bar,

' ing diverging extregamties, with of a series of holding-anchors mounted therebraoo the other side-of the bar and provided on consisting of sheet-metal strips bent to embrace the bar and having dutWardly-extendholding-slips I adapted to embrace'the bar on its opposite side and to engage said 'tially as set forth.

In testimony whereof I aflix my signature in presence of twosowitnesses.
